法兰式套管

transformer flange bushing

法兰式套管主要特点如下：

The main features of transformer flange bushing are as follows:

1.无渗漏，密封性能好。套管密封结构选择在金属法兰之间，密封后上下法兰无缝隙，胶垫无外漏，避免了因胶垫外露而产生的老化、龟裂现象，所配胶垫为双线密封胶垫，确保密封可靠。

No leakage and good sealing performance. Sealing structure of bushing is selected between metal flanges. After sealing, there is no gap between upper and lower flanges and no leakage of rubber pads, which avoids aging and cracking caused by exposed rubber pads. The rubber pads are double-line sealing rubber pads to ensure reliable sealing.

2.具有高抗震和耐破性、机械强度好，套管铝合金法兰采用航空技术生产，瓷套与法兰采用特殊工艺经卡装后粘接在一起，机械强度高、耐腐蚀、外型美观，适合特殊环境。

It has high earthquake resistance and burst resistance and good mechanical strength. The aluminum alloy flange of bushing is produced by aviation technology, and the porcelain bushing and flange are stuck together after being clamped by special technology. It has high mechanical strength, corrosion resistance and beautiful appearance, and is suitable for special environment.

3.无局部放电，电气性能好。产品经优化设计，使电场更均匀，无悬浮电位，局部放电小于10pc.

No partial discharge and good electrical performance. After optimized design, the electric field is more uniform, there is no floating potential, and the partial discharge is less than 10pc.

4.结构合理，安全性能好。产品设计载流裕度大，采用自体散热和油循环散热设计，减少和避免了导电杆在长时间或超负荷运行时过热和烧蚀现象的发生。

Reasonable structure and good safety performance. The product design has a large current-carrying margin, and adopts the design of self-cooling and oil circulation cooling, which reduces and avoids the overheating and ablation of the conductive rod during long-time or overload operation.

5.安装方便，通用性好。套管根据国内行业特点及惯例设计，可与现有套管实行互换，通用性好，便于选用和产品的布置。法兰式套管减少了安装附件，减轻了劳动强度。

Easy installation and good universality. The bushing is designed according to the domestic industry characteristics and conventions, and can be interchanged with the existing bushing, which has good universality and is convenient for selection and product layout. Flanged bushing reduces installation accessories and labor intensity.
